Site Site-Specific Standard Order (Particulates): Specific Standard Order (Particulates): Performance Review Performance Review – Additional Items Additional Items Community complaints since the last CLC meeting: A. Complaints registered with HIEA and MOECC; shared cleanup costs 1. Beach Blvd. - Black dust (Jan. 12, 2018) – Strong wind and coal unloading at AMD and Stelco on Dec. 7 – 9, 2017 2. Beach Blvd. (2 homes) - Black dust (May 4, 2018) – No specific incident identified 3. Beach Blvd. – Dust (May 25, 2018) – No specific incident identified B. Observations of Stelco emissions 1. Dock’s coal dust on Mar. 18, 2018 (L. Lukasik) – Emission of dust when the coal scraper dug into the base of a coal pile with more fines. 2. Black Battery emissions on Apr. 7, 2018 (L. Lukasik) – Resulted upon opening the door to push oven 713. 3. Stack, Battery and quench emissions on May 13, 2018 (L. Lukasik) 4. Purplish stack emissions on May 24, 2018 – Short black emissions upon opening the door to push oven 724

NO NO X emission emission Conclusion : Factors affecting the formation of NO 2 that caused the brown emissions which gradually get darker nearing the Battery reversal are: the COG composition in terms of NH 3 content, COG combustion conditions, flame temperature, O 2 content, moisture, atmospheric and photochemical conditions around the stack outlet. How to address the issue : How to remove NO 2 by subjecting or burning it in a fuel-rich flame, e.g., heating enhancement, stack burner activation, and, maximizing By-Product recovery of ammonia. Resolution : The stack burner has been consistently on since May 16, 2018. Battery heating is supplemented by natural gas since May 24, 2018. Since these were implemented, the occurrence of brown stack emissions at sunrise and before sunset had been significantly reduced.

Pushing Emission Pushing Emission Conclusion : Inadequate temperature in the coke oven during the coking process, resulting in “green coke”. How to address the issue: i. Battery heating has been supplemented by natural gas since May 24, 2018. ii. Permanent crew to clean the heating system and flues. Resolution : Similar cases have significantly reduced.

Quenching Emission Quenching Emission Conclusion : Inefficient removal of particulates during the quenching of coke. Probable Cause : As designed, the quench tower has baffles that capture most coke particulates upon release by the rising steam as water gets in contact with hot coke. If these baffles are damaged or missing, particulate removal is ineffective, resulting in particulate emissions. Resolution : New baffles were completely installed May 2017. Review and increase the frequency of routine maintenance of the baffles, water nozzles, demister pump, dezurik valve and the water supply system.

Benzene

Sampling Strategy – Benzene The goal is to identify additional fugitive sources of benzene to assess the quantity and frequency to answer the question, Is the source significant and can it be reduced? • Review the process stream to identify where benzene might report • Monitor – Hand-held with Photoionization Detector for VOCs (specific for benzene) • Monitor the process – upwind, downwind – fugitive and potential emission points such as valves, vents • Monitor at various times – normal operations, maintenance activities
